Why do Christians become Christians?

[SteveII]

I am not trying to prove anything. I am defending the OP observation that adult (I am now clarifying) conversion to Christianity is based on what I wrote about Jesus and not 1) biological and social evolution and 2) cultural influence.

Missionary conversion success illustrates that there must be something about the message that resonates with the person rather than 1) and 2) above.

So what is adult conversion to Islam based on, with 2) as the given?

It's clearly not the message when it doesn't seem to matter what the message is. It's the help. Come for the food and medicine, stay for the religion.

The main reasons for Islam’s growth ultimately involve simple demographics. To begin with, Muslims have more children than members of the seven other major religious groups analyzed in the study. Each Muslim woman has an average of 3.1 children, significantly above the next-highest group (Christians at 2.7) and the average of all non-Muslims (2.3). In all major regions where there is a sizable Muslim population, Muslim fertility exceeds non-Muslim fertility.

The growth of the Muslim population also is helped by the fact that Muslims have the youngest median age (23 in 2010) of all major religious groups, seven years younger than the median age of non-Muslims (30). A larger share of Muslims will soon be at the point in their lives when people begin having children. This, combined with high fertility rates, will accelerate Muslim population growth.

Do you a link that shows data on adult conversions to Islam?
